Application December 17, 1931, Serial No. 581,621

3 Claims.

This invention relates to improvements in tobacco pipes. The draught or suction of such pipes is frequently impaired through a clogging which takes place at the bottom of the pipe-bowl, and particularly at the junction of the bowl and the pipe stem, which clogging is due to the continual accumulation of various ingredients distilled out of the tobacco during the smoking. Those accumulated ingredients have to be frequently scraped out of the pipe-bowl, as besides impairment of the suction, they also form hard or viscous masses which seriously vitiate the taste of the tobacco.

The principal object of our invention is to provide a tobacco pipe with improved and efficient means for remedying the above mentioned disadvantages.

Another object is to provide a simplified, inexpensive, reliable, and efficient absorbent means with a retaining device therefor for a pipe bowl, both of which may be readily, rapidly, and conveniently discarded from the bowl for renewal of the absorbent.

Other objects and advantages will hereinafter appear.

In the accompanying drawing;-

Figs. 1 and 2 are longitudinal cross-sections of pipe bowls equipped with absorbent tablets and retaining devices therefor, both of which forms are modifications of this invention.

Figs. 3 and 4 are plan views of the pipe bowls, with the absorbent tablets and sustaining devices shown in Figs. 1 and 2 respectively.

Figs. 5 and 6 are perspective views of further modifications of the improvements consisting of the invention herein, with the absorbent tablets shown in dash and dot lines.

In the lower portion of the bowl 1 of the tobacco pipe 2 is located a tablet 3 made of any suitable absorbent and non-combustible material, such as mineral fibre. Said tablet may be of any suitable shape, configuration, or contour, as round, hexagonal, semi-spheroidal, etc., as shown, with one or more perforations 4 and one or more vent grooves 5. The tablet 3 is retained in requisite position within the bottom of the bowl by means of a retaining device 6, Figs. 1, 3, which consists of a metallic band having upper and lower spring leaves '7, 8 that grip the tablet in the manner shown to sustain it, and a springy arm 9 which projects laterally and normally bears pressingly and resiliently against the wall 10 of the bowl as indicated. This pressure of spring-arm 9 against the wall of the bowl compels the opposite side 11 of the tablet to bear correspondingly pressingly against the opposite side of the wall of the bowl, in which manner the tablet is firmly and efficiently retained in proper position in the bottom of the pipe-bowl, and any accidental dislocation thereof is pre- 0' eluded. When it is required to discard the tablet 3 for renewal of a fresh tablet, the user may merely insert a knife blade or any other suitable implement into the pipe-bowl and therewith demolish the tablet, whereupon the broken tablet and its retaining device 6 will automatically drop out and clear the bowl, ready for the reinsertion of a fresh tablet and retaining device.

According to the modification shown in Figs.

2, 4, the retaining device 12 is molded directly within the interior of the tablet 3, for thereby sustaining the tablet, and a springy arm 13 thereof projects outwardly from the tablet and bears laterally pressingly against the wall of the pipebowl, in the same manner as that performed by the arm 9 of the device 6, for retaining the tablet in requisite position. It will be evident that in this case the opposite side of the tablet similarly presses against the wall of the bowl, whereby demolishing of the tablet causes it to drop out of 8 the bowl together with its retaining device which forms part thereof.

With the above provisions the tobacco carried in the pipe above the tablet has its objectionable ingredients distilled out therefrom by the absorbent material. All clogging of the pipe junction 14 is in this manner prevented and impairment of the suction obviated, and the suction is further improved by the provision of the numerous vents or air passages 5 and perforation 4 of the tablets 3. With the use of these improvements, the bottom of the bowl will be always found dry and free from all objectionable hard or viscous foreign matter which is ordinarily found in pipe bowls and vitiates the taste of the smoking.

In the modification shown in Fig. 5 the retaining device 6a is made of a single piece of wire 14a bent to form upper and lower rings 7a, 8a for resiliently grasping the absorbent tablet, and the terminal 9a of the wire projects laterally to bear pressingly and resiliently against the wall of the bowl to thereby retain the device and tablet in requisite position. In the modification illustrated in Fig. 6 the retaining device is similar to that shown in Fig. 1, but its lateral projecting arm 91) is formed by stamping it out of the upright portion 15 which connects the grasping leaves '7, 8.

Variations may be resorted to within the scope of the invention.

Having thus claim:

1. The combination with an absorbent tablet for the lower portion of a pipe bowl, of a frame adapted to sustain said tablet, said frame including a spring portion adapted to bear laterally against the wall of the bowl and compel said tablet to itself bear oppositely against said wall to maintain it in place, neither said frame nor tablet being of itself large enough to be wedged in the bowl, and said frame and tablet dropping out of the bowl upon destruction of the tablet. I

2. An absorbent tablet for the lower portion 0 a pipe bowl carrying a spring adapted to bear laterally against the wall of the bowl and compel said tablet to itself bear oppositely against said wall to wedge it in place, neither said spring nor described our invention, we

enough to be wedged in the bowl, and said tablet and framing dropping out of the bowl upon destruction of the tablet.
